“…This result could also be associated with more complete coverage of the soil surface with the chickpea and wheat residue covers compared with those of corn and sunflower. Amini, Ebrahimi, and Dabbagh Mohammadi Nasab (2020) also reported that using wheat straw mulch in Moldavian balm ( Dracocephalum moldavica L.) decreased the weed density by 62%, compared with that in the weed‐infested treatment. All crop residue covers indicated higher inhibitory effects on seedling emergence of the Tabriz population compared with those on the Meshginshahr population, which could be attributed to the larger seeds of the Meshginshahr population.…”

Astrodaucus orientalis is a weed species in cropping systems and rangelands in Iran. The effects of temperature, light, NaCl concentration, water potential, seed burial depth and crop residue cover were assessed on seed germination and seedling emergence of two populations of A. orientalis from Ardabil (Meshginshahr population) and East Azarbayjan (Tabriz population) provinces of Iran. The A. orientalis populations indicated different responses to environmental factors and burial depth. In the Tabriz population the greatest germination (88.5%) was observed in 20/12°C day/night temperature but in the Meshginshahr population (83.2%) it was obtained in 24/16°C day/night temperature. Over a broad range of light period (10–24 hr light) germination was 74–83%, but it decreased (less than 37%) under 24 hr dark in both A. orientalis populations. With respect to water potential, the C50 parameters were −0.62 and − 0.49 MPa for Tabriz and Meshginshahr populations, respectively. The D50 parameters (the burial depth that caused 50% decrease in emergence) for Tabriz and Meshginshahr populations were 2.42 and 3.13 cm, respectively. Generally, the results showed that emergence of both populations of A. orientalis was delayed as depth of burial increased up to 4 cm and in cropping systems a shallow tillage that locates the seeds to >4 cm of depth in soil could be used in order to suppress seedling emergence. Our findings also could be useful in integrated management of A. orientalis in winter annual crops and rangelands.

“…The D. moldavica plants grown and utilized in this study also belonged to the above chemotype. Other previously reported chemotypes of D. moldavica include: the geranyl acetate + geranial + geraniol one [ 42 , 47 , 48 , 49 , 50 , 51 ], the 1,8 cineole + 4-terpineol [ 52 ], and the linalool + geranial + fenchone [ 53 ].…”

Steam distillation was used for the isolation of Dracocephalum moldavica L. (Moldavian dragonhead) essential oil (DMEO). This aromatic herbaceous plant is widespread across the Northern Hemisphere regions and has been utilized in health-improving studies and applications. In addition to the DMEO, the hydrolate (DMH), a byproduct of the distillation process, was also collected. The DMEO and DMH were analyzed and compared in terms of their chemical composition, as well as their in vitro biological activities. The main component in DMEO was geranyl acetate, while geranial was dominant in DMH. The DMEO demonstrated better antioxidant and antimicrobial activities compared with the DMH against Staphylococcus aureus, Escherichia coli, Salmonella Typhimurium, and Listeria monocytogenes, which represent sources of food-borne illness at the global level. The DMEO and DMH show promise as antioxidant and antimicrobial additives to various products.

“…The quantity and quality of the essential oils varies depending on genetics [38] and environmental conditions [18]. One of the most important issues is strongly related to weed management and control, which directly influence the biomass yield and essential oil content [39].…”

Medicinal and aromatic plants hold a high share of interest in Romania. To offset the harvesting of spontaneous flora and ensure the sustainable conservation of natural resources, the cropping of highly valuable plants of interest represents a priority for the current agricultural system. This study was conducted due to the need for more balance in species exploitation. Therefore, it assessed the emergence dynamics, leaf appearance, growth and development of the plants depending on row spacing and plant distance. The research was conducted at the INCDCSZ Brașov, within the Technology Department, Laboratory of Medicinal and Aromatic Plants. The density of planting is the most important factor. Plants sown in continuous rows showed the highest yields of fresh and dry herbs, especially when the distance between the rows was set to 25 cm. Row-by-row distances of 50 cm ensure average values for all growth and development parameters. An increase in the row-by-row distance up to 70 cm drastically reduced the dry biomass up to 7.89 t ha−1 in continuous rows, followed by a 2 and 2.5 t ha−1 decrease for 15 cm and 25 cm plant-by-plant distances, respectively. Continuous row planting and a 25 cm row-by-row distance negligibly reduce the climate impact on growth and development. Greater spaces between plants leads to an average increase in individual development, but with a decrease in the total potential yield.
